Figure 67: DC Power Cable Connections

NOTE: DC power cables must not block access to router components or
drape where people could trip on them.
The DC power supplies in slots
feeds derived from feed A, and the DC power supplies in slots
powered by dedicated power feeds derived from feed B. This configuration provides the
commonly deployed feed redundancy for the system. Most sites distribute DC power
A/B
through a main conduit that leads to frame-mounted DC power distribution panels, one
of which might be located at the top of the rack that houses the router. A pair of cables
(one input and one return) connects the field-wiring terminals to the power distribution
panel.
